PORTABLE WALL SECTION FOR HOUSE BUILDING.

Application filed June 2,

To all whom t may concern.'

Be it known that I, KARL I-IELMnR ARoNssoN, a subject of the King of Sweden, and resident of Huvudsta, in the Kingdom of Sweden, have invented certain new and useful Improvements in Portable Wall Sections for House Building, of which the following is a specification.

This invention relates to wall-sections for house-building and similar purposes, which may be manufactured in factories. According to the invention each of the said sections Vcomprises fra-mes fixed on opposite sides of a plate or panel, which does not extend outward to the outer edges of the said frames, grooves being thus 'effected in the edges of the sections. In building` up houses from sections thus constructed feathers are forced into the grooves of two adjacent sections or into the groove of the section and a corresponding groove provided in a roof-sill or bonding-sill, a post, window-frame, doorcase, etc.. for fixing the section. Un the sides of the frames sheathings may be fixed.

Figs. l. and 2 of the accompanying drawing show in a side view and in a vertical sect-ion respectively a wall-section arranged in accordance with this invention. Fig. 3 shows in a horizontal -section a part of a building composed of wall-sections, ar-

lranged in accordance with the invention.

l. is a panel or plate composed of two or more layers of boards placed cross-wise, the said 'layers being connected by a glue or paste which is insoluble in water. On op. posite sides of the said plate I rails 2 and 8 are fixed, extending along the edges of the plate and constituting' together frames. The said rails extend for a distance outside the es iges of the plate, so that grooves 4i areprovided between the same, said grooves extending along the edges respectively of the plate. As thehouse is built up sections thus constructed are placed edge by edge, a feather 5 being then forced into the grooves facing each other. The said feather then connects the sections and renders the joint between the same very weather-tight. In the window-frame 6 shown in Fig. 3 aV etc.

groove is provided corresponding to the groove of the adjacent wall-section. The said wall-section is fixed to the windowframe by a feather, forced into the grooves of the wall-section and the frame. In the same manner wall-sections may be fixed to door-cases, posts, roof-sills, bonding-sills, Att the corners of the house one (3) of the frames of the wall-sections may be provided with a lateral tongue 7, Fig. 8, which engages the groove of the second wall-section. To the plate l or inside the frames 2 and 3 transversal rails 8 preferably are fixed. In the factory or on the place, where the house is built up, inner and outer sheathings vare fixed to the frames, the spaces between the said sheathings and the plate l being by the transversal rails 8 divided into cells containing air. Owing to the said cells the heat in the said spaces will not be accumulated at the top part of the spaces but is more uniformly distributed upwards in the wall-seotions. Two or more wall-sections may, evidently, be located side by side and fixed to each other, if necessary, or the wall-section may comprise two or more plates together with frames, in which case there is a corresponding number of grooves extending round the wall-section adapted to receive tightening feathers.

Portable wall-sections for house-building comprising a plate or panel and rails fixed on opposite sides of the said panel, at the edges of same and extending outside the edges of the plate, the said rails effecting grooves, in which and corresponding grooves in thel adjacent wall-section, roof-sill, bonding-sill, window-frame, door-case, etc., tightening feathers may be introduced for fixing the said sections.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
